近年来,随着人们对节约常规能源和开发新能源的日益重视,被动式太阳房正大批投入使用。在冬季,为了提高太阳房的节能率,往往对围护结构进行严格的密闭处理。这一方面表现在设计时对集热窗进行密封和对其余墙体采取绝热措施;另一方面表现在使用时尽量少开启门窗。这样做的后果是:室内通风换气次数减少、有害物质富集、空气品质下降,引起居住者的不适,带来太阳房内环境问题。因此,及时开展太阳房室内空气品质及其影响的研究,并探讨改善太阳房室内空气环境的途径,是保证太阳房顺利健康地推广的重要方面。
In recent years, passive solar houses are being put into use as people pay more attention to saving conventional energy and developing new energy. In winter, in order to improve the energy efficiency of the solar house, the enclosure structure is often closed tightly. On the one hand, the seal of the heat-collecting window and the insulation measures on the other walls are taken into account during the design; on the other hand, the doors and windows are opened as little as possible during use. The consequences of this are: reduction in the number of indoor ventilation, accumulation of harmful substances, declining air quality, causing discomfort to occupants, and environmental problems in the solar home. Therefore, the timely development of indoor air quality and its effects in solar houses and the ways to improve the indoor air environment in the solar houses are important aspects to ensure the smooth and healthy promotion of solar houses.
